Filed: 1979-02-26
Abstract: PURPOSE: To enhance efficiency of collecting small dust particles by installing a flow-rectifying member having a sectional area larger than the inlet area, at upstream of a cyclon.  
     CONSTITUTION: A flow-rectifying member B has a sectional area larger than that of waste gas pipe A and has an internal rectifying lattice 1. Dust-containing gas G is geadually decreased in speed in the tapered area b 1 , is rectified into axial flow by the rectifying lattice 1 in the maximum expanded area b 2 , so that small dust particles in gas G is prevented from fluctuation. The gas is then accelerated in the contracted area b 3  and flows into the separator body (C). In the internal of the separator body (C), are installed boss 2, guide blade 3, and support member 4. The guide blade 3 makes the gas a swirling flow and its centrifugal force causes dust to gather on the internal surface of the body (C). The dust flows through the separation groove 6 to the separation chamber 5 and is discharged from the high-concentration dust-containing gas outlet 7.

Title: Polyol composition and its production
Inventor: OZAWA SHIGEYUKI
IPC: C08G12/00
Filed: 1982-02-16
Abstract: PURPOSE:A polyol composition excellent in dispersion stability, consisting of an aldehyde polycondensate at least part of which is bonded to an addition polymer. CONSTITUTION:A polymer composition for the production of polyurethane which contains an aldehyde polycondensate component and an addition polymer component and in which at least part of the aldehyde polycondensate (e.g., melamine/formaldehyde polycondensate) is bonded to the addition polymer (e.g., acrylamide/acrylonitrile copolymer). For example, when melamine and formaldehyde are reacted together in a polymer polyol containing acrylamide/acrylonitrile addition copolymer, a melamine polycondensate is formed and at the same time, formaldehyde is condensed with the amide groups in the acrylamide structural units to bond the addition copolymer to the melamine polycondensate. As compared with the dispersion stabiity of a conventional melamine polycondensate which is dispersed simply in a polyol, that of the present polymer in a polyol is markedly improved.
